Heads up - another asteroid just flew over the Earth.
Asteroid 2014 DX110 passed above our heads from a distance of about 217,000 miles.
That sounds quite a long way - but it's actually closer than the average distance to the Moon.
The 100-foot-wide rock was discovered just last week on February 28, Nasa said.
It presents no threat to Earth, but it does illustrate the continued need to improve our tracking of Near-Earth Asteroids, and to research new means to try and divert one in the rare event that it came just too close for comfort.
